What it does

The extension uses Vertex AI to analyze your staged Git changes and write a professional commit message.

It is designed to produce messages in Conventional Commits style with:

• an imperative subject line
• no trailing punctuation
• a short subject and more descriptive body
• a proper commit type such as feat, fix, refactor, docs, or chore

How to run it

The command is available in the Git SCM toolbar as a wand icon and also in the Command Palette as:

• Vertex AI Models Chat Provider: Generate Commit Message

Requirements

• The workspace must use Git with staged changes.
• The vscode.git extension must be available.

What it uses

The message generator sends your staged diff to Gemini 3 Flash model and streams the response into the Git commit input box.

It also records usage metrics so the cost dashboard can show the token impact of the request.

Benefits

• Saves time on commit message writing
• Encourages consistent commit formatting
• Works without API keys, using your configured Google Cloud project credentials
